1 Introduction
1.1 Functional overview
The Neutronics Model 3100 Compact Series analyzer is a microprocessor-based instrument for oxygen
measurement and process control applications.
The Model 3100 analyzer is designed for use with a separate Neutronics Remote Sensor Module (see
Figure 1). The RSM features the Neutronics ZR100 rapid–response zirconium oxide (ZrO2) oxygen
sensor, a ceramic, solid-state device with an extremely fast response to oxygen, a wide measurement
range, and a robust design. It is responsive to changes in the partial pressure of oxygen of a sampled
gas in the range of 0.1 PPM to percent concentration of O2. Unaffected by dry atmospheres and
extremely cold storage temperatures (or power down situations in cold environments), it has an indefinite
shelf life.
1.2 Features
The Compact Series analyzer modules are designed to be flush mounted onto the surface of a control
panel or console. The separate Remote Sensor Module can be mounted close to the sampling point to
ensure the fastest response possible. Other key features include:
0.1 ppm to percent measurement range
Two user-adjustable oxygen alarms with configurable relay outputs for process control use
Two analog outputs: 4-20 mA and 0-1, 0-5, or 0-10 VDC
Auto-ranging or fixed range oxygen measurement (VDC output provided for auto-range
identification)
RS-232 digital interface
